Hoary willowherb
Epilobium parviflorum
Hoary willowherb is a hardy perennial wildflower that thrives in moist, open or partly shaded habitats such as stream banks, ditches, and meadow edges. It produces delicate pink flowers from midsummer to early autumn that attract bees and butterflies, and has a long history of medicinal use in European herbal traditions. Plant in moist, fertile soil and cut back after flowering to prevent excessive self-seeding.
